ING CORPORATION, 0F NEW YORK, N. Y., A CORPORATION n 'BLASTER SUPPORT Continuation of application Serial No. 618,008, led February 9, 1923. This application led January 1925, Serial No. 3,605, and in Canada .Tune 25, 1923. v

This invention relates to a plaster support,

An object of the invention is to provide a plaster vsupport which Awill hold the soft plaster applied thereto and which will reinforce this plaster after it has hardened.

Another object is to provide a support with reinforcing bars whic'hwill become substantially entirely imbedded in the plaster and which will reinforcexand brace the plaster both-vertically and transversely.

Another obj ect is to provide a plaster support with transverse reinforcing bars which will keep the plaster from slippage or displacement.y

Another object is to provide a plaster support with reinforcing bars which will hold the soft plaster from outward displacement.

. Another object is to provide a plaster support which, with'the plaster, will produce a damp-proof, fireproof, vermin-proof, heat in- Y sulating and sound deadening wall.V

Other objects of the invention will become apparent from tthe embodiment hereinafter set forth. a

According to the invention as it is herein set forth, it comprisesa corrugated board having on the face thereof vertical and transverse reinforcing members or bars which become entirely embedded within the plaster substantially throughout the length thereof andl thereby reinforce'the plastery both vertically and transversely.

The vertical reinforcing bars are fastened to the board at the crest ofthe ridges and span the furrows between the saine.

' The transverse reinforcing bars are arranged in the furrows and held in position therein lby the vertical reinforcing bars.

The softplaster is applied to the corrugated board and overthe vertical and transverse reinforcingbars and thereby these bars become substantially 'embedded in the plaster and reinforce it both vertically and transversely.

' The corrugated board and the transverse reinforcing .bars both support the `soft plaster vertically and thereby keep it from slipping downward. The .vertical and transverse reinforcing bars hold the soft plaster on the board and keep it from outward displacement. f

The transverse-reinforcing bars are ordi, narily fiat metal strips which have on each edge thereof alternate upward. and downwardflanges, the flanges on onesidebeing arranged to overlap the flanges on the'other side so as to reinforce the bar and give it rigidity.

kThese flanges, .particularly the outer flanges, serve to hold the soft plaster' from outward displacement.

The invention embodied in the plaster support'herein set forth for the purpose of explanation is susceptible of various obvious modifications.

Fig. 4 is a sectional view on the line 4-4 of Fig. 2 showing the way the vertical reinforcing Iwires or bars are fastened to the board by the wire on the back thereof. y

Fig. 5, is a view in perspective ofthe transverse reinforcing bars.

The plaster support comprises, in general, a corrugatedl vboard l having on the `face thereof vertical reinforcing wires or bars 2 and transverse reinforcing bars 3.

y The corrugated board is ordinarily made of fibrous material, which is coated, impregnated or otherwise treated with asphaltum or other lnaterial which will make it dampproof, vermin-proof and preserve the same. The vertical reinforcing wires rest upon the ridges of the corrugated board and span the furrows between the same. l

They are held in Vplace by holding wires 4 arranged on the back of the corrugated board in alignment therewith andhaving loops 5 which' pass through the crests of the ridges and are hooked or pass over the vertical reinforcing wires.

These holding Wires, in addition tofastenbrace and reinforce the corrugated board. e

Thetransverse reinforcing bars are ordinarily arrangedin' alternate furrows andrew tained thereinbvthe vertical reinforcing bars.

They are preferablyv in the 'forni of va flaty metal strip 6 which has alternategilpwardi e and downward flanges 7011 the inner and edge overlapping'the flanges Vonthe other eds@- ...Y They are'of ysuchl width as to support the plaster vertically and are braced, `reinferced and 'given rigidityV by' the fianges thereof.'

' rllhe"plaster support is ordinarily fastened in 'position onlthe'wall or ceilingby staplesl 8 whichipass over 'both the vertical' wires ,and transverse barsfa'tpoints'where they cross.

The :transverse 'bars with'the. alternate upward anddownward flanges expand an'dcontractfinsucliwway 'as .nottocause line cracks.v

i The I corrugated board is preferably flush with .the transverse bars'at one vendl and projects' beyond these. bar s'at the .other end'so that` adjacent boards may be overlapped and the vtransverse bars brought together,

As the vertical and transverse.v reinforcing bars 'are :arranged 'throughout their length on'jtheffr'ont ofthe corrugated board, they become substantially entirely embedded withinthe pl'asterfand thereby firmly reinforce on aceiling.
